Mobile-first design: why it matters when you buy a website

Google indexes the mobile version of a site first. What to check on a phone before you buy a website.

A site that works badly on phones is a problem you'd be buying.

The mobile reality

  • A large share of web traffic is mobile, and the site's analytics show how much of its own is.
  • Google uses mobile-first indexing, so it mainly indexes and ranks the mobile version of a page.
  • Slow pages lose visitors. Test the load speed on a phone connection.
  • People shop on their phones, so an awkward mobile checkout costs sales.

What to check

Is the design responsive or adaptive? Responsive design adjusts to any screen size; adaptive design serves fixed layouts for specific devices. Responsive is usually better.

Apple's guidelines suggest touch targets of at least 44 by 44 points.

Body text should be at least 16px on phones.

The menu should be reachable with one hand, often near the bottom of the screen.

Form fields should bring up the right phone keyboard, such as the email keyboard or the number pad.

Testing before you confirm

If you buy a website through escrow, test it on your phone before you confirm receipt:

  • open every page
  • try every form and button
  • check the load speed
  • make sure images load
  • go through the checkout or payment flow

If it doesn't work well on mobile, don't confirm. Open a dispute, and a moderator will review the evidence and decide.
